Trademark
B)
Hallmark
C)
Brandmark
D)
Agmark
A hallmark is the official mark stamped on precious metals like gold, silver, platinum, etc., to certify their purity and fineness. Therefore, option (b) is correct. Trademark and brandmark identify a company or product, not metal purity. Agmark is a certification mark for agricultural products in India, not for precious metals.
To obtain full benefits of demographic dividend, what should India do?
A)
Promoting skill development
B)
Introducing more social security schemes
C)
Reducing infant mortality rate
D)
Privatisation of Higher education
Demographic dividend means economic benefit arising from a large working-age population. India can obtain the full benefit only if this population is productive and employable. Therefore, promoting skill development is the most important step. It improves employability, productivity, and income generation.
Why others are less appropriate: (b) Social security schemes are helpful for welfare but do not directly convert the young population into productive human capital. (c) Reducing infant mortality is important for public health, but demographic dividend mainly depends on effectively using the working-age population. (d) Privatisation of higher education is not a necessary condition for demographic dividend and may even reduce access.
Which of the following is the chief characteristic of mixed farming?
A)
Cultivation of both cash crops and food crops
B)
Cultivation of two or more crops in the same field
C)
Rearing of animals and cultivation of crops together

None of these
Mixed farming means a farming system in which crop cultivation and livestock rearing are carried on together on the same farm. Therefore option (c) is correct. Option (a) refers to growing different types of crops, not mixed farming. Option (b) describes multiple cropping/intercropping. Option (d) is incorrect because option (c) is the right answer.
Acid rain is caused by the pollution of environment by
A)
Carbon dioxide and nitrogen
B)
Carbon monoxide and carbon dioxide
C)
Ozone and carbon dioxide
D)
Nitrogen oxide and sulphur dioxide
Acid rain is mainly caused by the release of sulphur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere. These gases react with water vapour and oxygen to form sulphuric acid and nitric acid, which fall with rain. The other options mention gases that do not primarily cause acid rain.
The Prime Minister of India, at the time of his/her appointment
A)
Need not necessarily be a member of one of the Houses of the Parliament but must become a member of one of the Houses within six months
B)
Need not necessarily be a member of one of the Houses of the Parliament but become a member of the Lok Sabha within six months
C)
Must be a member of one of the Houses of the Parliament
D)
Must be a member of the Lok Sabha
Under Article 75(5) of the Constitution of India, a minister who is not a member of either House of Parliament for any period of six consecutive months ceases to be a minister at the end of that period. This rule also applies to the Prime Minister. Therefore, at the time of appointment, the Prime Minister need not already be a member of Parliament, but must become a member of either the Lok Sabha or the Rajya Sabha within six months. Hence (a) is correct. Option (b) is incorrect because membership is not restricted to the Lok Sabha alone. Options (c) and (d) are incorrect because prior membership is not compulsory at the time of appointment.
Deficiency of which vitamin effects blood clotting?
A)
Vitamin A
B)
Vitamin D
C)
Vitamin K
D)
Vitamin B
Vitamin K is essential for the synthesis of several clotting factors in the liver, so its deficiency impairs normal blood clotting and may cause excessive bleeding.
Why others are incorrect: Vitamin A is mainly related to vision and epithelial health; Vitamin D is related to calcium metabolism and bone health; Vitamin B refers to a group of vitamins mainly involved in metabolism and nerve function, not specifically blood clotting.
Variations in the length of daytime and nighttimes from season to season is due to
A)
The earth’s rotation on its axis
B)
The earth’s revolution round the sun in elliptical manner
C)
Latitudinal position of the place
D)
Revolution of the earth on a tilted axis
The variation in the length of day and night during different seasons is caused by the earth’s axis being tilted (about 23.5°) and the earth revolving around the sun. Because of this tilt, different parts of the earth receive varying durations of sunlight in different seasons.
Why others are incorrect: (a) Rotation on its axis causes day and night, but not seasonal variation in their length. (b) The elliptical shape of the orbit is not the main reason for seasonal changes in day length. (c) Latitude affects how much variation a place experiences, but it is not the fundamental cause. Therefore, the correct answer is (d).
Which among the following is categorised as All India Service?
A)
Indian Audit and Accounts Service
B)
Indian Railway Service
C)
Indian Forest Service
D)
Indian Economic Service
The All India Services are services common to both the Union and the States. Presently, the three All India Services are Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Forest Service (IFoS). Therefore, Indian Forest Service is the correct answer. The other options—Indian Audit and Accounts Service, Indian Railway Service, and Indian Economic Service—are Central Services, not All India Services.
The oldest mountain in India is
A)
Satpura
B)
Nilgiri
C)
Vindhyachal
D)
Aravalli
The Aravalli Range is considered the oldest mountain range in India, formed in the Precambrian era. It is much older than Satpura, Nilgiri, and Vindhyachal. Therefore, option (d) is correct.
Formation of droplets of water and mercury are formed by
A)
Pascal’s Law
B)
Surface Tension
C)
Archimedes Principle
D)
None of these
Water and mercury form droplets because of surface tension. Surface tension makes the liquid surface behave like a stretched membrane and tends to minimize surface area, causing the liquid to gather into nearly spherical drops. Pascal’s law is about transmission of pressure in fluids, and Archimedes’ principle is about buoyancy, so neither explains droplet formation.
Which of the following is called laughing gas?
A)
Nitric Oxide
B)
Hydrogen Oxide
C)
Nitrous Oxide
D)
Ammonium Nitrate
Nitrous oxide (N2O) is commonly called laughing gas because it can produce euphoria and fits of laughter when inhaled. Nitric oxide is a different gas (NO), hydrogen oxide is water, and ammonium nitrate is a salt, not a gas.
Granite and gabbro are examples of which of the following rock?
A)
Sedimentary Rock
B)
Metamorphic Rock
C)
Igneous Rock
D)
None of these
Granite and gabbro are both intrusive igneous rocks. They form when molten magma cools and solidifies slowly beneath the Earth’s surface. Granite is typically light-colored and coarse-grained, while gabbro is dark-colored and coarse-grained. They are not sedimentary rocks (formed by deposition) or metamorphic rocks (formed by heat and pressure).
Plaster of Paris is made from
A)
Calcium Chloride
B)
Sodium Carbonate
C)
Gypsum
D)
Calcium Trisilicate
Plaster of Paris is prepared by heating gypsum (calcium sulphate dihydrate, CaSO4·2H2O) to remove part of its water content, forming calcium sulphate hemihydrate. Therefore, the correct answer is gypsum. The other options are incorrect because calcium chloride is a salt used for drying and de-icing, sodium carbonate is washing soda, and calcium trisilicate is related to cement chemistry, not Plaster of Paris.
A person stood alone in a desert on a dark night and wanted to reach his village which was situated 5 km east of the point where he was standing. He had no instruments to find the direction but he located a polestar. The most convenient way now to reach his village is to walk in the
A)
direction facing the polestar
B)
direction opposite to the polestar
C)
direction keeping the polestar to his left
D)
direction keeping the polestar to his right
The Pole Star indicates the north direction. If the village is 5 km east of his current position, he must walk towards the east. When a person faces east, the north direction lies to his left; equivalently, while walking east, the Pole Star will be on his left. However, among the given options, the standard directional relation used is: to move east using the Pole Star (north), he should keep north on his left. Therefore the correct choice should logically be 'keeping the polestar to his left'. Since the options require one answer, the correct option is (c), not (d).
Gas leaked in the Bhopal Gas Tragedy was
A)
Sodium Isothiocyanate
B)
Methyl Isocyanate
C)
Ethyl Isocyanate
D)
None of these
The poisonous gas leaked during the Bhopal Gas Tragedy in December 1984 was Methyl Isocyanate (MIC), a highly toxic chemical used in pesticide manufacture at the Union Carbide plant. Hence option (b) is correct. Option (a) is incorrect because Sodium Isothiocyanate was not the leaked gas. Option (c) is incorrect because Ethyl Isocyanate was not involved in the disaster. Therefore, option (d) is also incorrect.
Name the Prime Minister of UK who granted independence to India, Pakistan, Ceylon and Burma in the year 1947
A)
Clement R Attlee
B)
Winston Churchill
C)

The correct answer is Clement R Attlee. He was the Prime Minister of the United Kingdom from 1945 to 1951, and during his tenure British India was partitioned and independence was granted to India and Pakistan in 1947. Burma also became independent in 1948, and Ceylon in 1948, under the Attlee government’s decolonisation policy. The other options are incorrect: Winston Churchill opposed Indian independence, Anthony Eden became Prime Minister later in 1955, and Harold Macmillan became Prime Minister much later in 1957.
